From a working day to a client bill
A freelancer’s hours do two jobs. They explain what the client is paying for, and they show whether an assignment was worth the time it consumed. A tool that records the day but leaves both calculations to a spreadsheet solves only part of that problem.
Harvest joins time and invoicing in one application. Toggl focuses this comparison on daily recording, My Hours on project timesheets, and Teetrack on rates, budgets, and reports for an existing billing process. The choice depends on where the work becomes difficult: remembering the hours, organizing them by assignment, or preparing the amount to charge.
This guide is published by Teetrack, which is included in the comparison. We checked the linked vendor documentation on September 18, 2026. The recommendations are based on that research; we have not tested these products side by side.
| Tool | Best fit | Plan / starting point | Main limitation |
|---|---|---|---|
| Harvest | Time and invoices together | Free: 1 seat and 2 projects | More concurrent projects require paid access |
| Toggl | Recording a varied working day | Free entry; paid billable rates | Check the billing features you need |
| My Hours | Project-based timesheets | Free entry; Basic and Pro upgrades | Rates, budgets, and approvals vary by tier |
| Teetrack | Budgets and billing reports | Free tracking; Business or Pro for billing | Free: 5 projects and 90-day history |
1. Harvest: Time and invoices together
Harvest records hours and expenses and uses them in invoices. This matters when preparing a bill currently means copying a time report and adding receipts in a second application. Keeping those inputs together can reduce that transfer, especially for freelance work that includes both hourly fees and reimbursable expenses.
Free provides one seat and two projects. That is enough only while the workload fits the project allowance, even if every project belongs to the same client. For more concurrent assignments, the paid plan and any usage charges become part of the cost of keeping invoicing in the same tool.
2. Toggl: Recording a varied working day
Toggl’s timers and calendar connections cover work that moves between delivery, calls, and administration. For a freelancer who already likes their invoicing software, the benefit is a record of the day that can be reviewed before billing. Separating client work from unpaid business development also makes the total workload visible, rather than reducing the week to the hours that appear on invoices.
Billable rates require a paid plan. Without them, the time record still needs a separate calculation before it becomes an amount to charge. That can be acceptable for a few straightforward invoices, but becomes more work when clients have different rates.
3. My Hours: Project-based timesheets
My Hours organizes time around projects and tasks, which helps when a freelancer needs to distinguish stages within an assignment. Research, production, and revisions can belong to the same project while remaining separate activities. That breakdown can explain why a fixed-fee job took longer than expected, even when the invoice itself contains a single amount.
The plan determines how far the financial analysis goes. Basic includes a basic billable rate, while Pro adds more detailed rate and budget calculations. A project timesheet answers where the hours went; pricing those hours or controlling a spending allowance requires the relevant paid features.
4. Teetrack: Budgets and billing reports
Teetrack’s paid plans connect project hours with rates, budgets, and CSV/PDF reports for another invoicing system. Suppose an hourly assignment has a EUR 1,000 budget and a rate of EUR 100. Eight billable hours consume EUR 800, leaving EUR 200 under those assumptions. That comparison gives the freelancer a reason to discuss further work before preparing the invoice.
The report supplies the billing inputs; the invoice remains in the existing finance application. Free excludes rates, budgets, and exports, so this use requires a paid plan. It is most relevant when the invoicing process already works and the missing piece is reliable project information.
Choose the part of billing you want to simplify
Harvest is the direct choice here for keeping hours, expenses, and invoices together. If invoicing already works elsewhere, the question becomes how much detail must reach that system: a time record from Toggl, a task breakdown from My Hours, or a rated project report from Teetrack.
Include your unpaid work in the decision. A tool that explains both the client’s bill and the rest of your working week gives you a better basis for quoting the next assignment.
